To all whom 'it may concern:

Be it known that I, DEONARD F. SCHMIDT,

a citizen of the United States, residing at.

Minersville, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Clutch-Bolts; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to improvements in clutch bolts.

The object of the invention is to provide a bolt of this character which is so constructed that the threaded portion thereof will be covered and protected and so arranged that the head of the threaded portion will not come into engagement with, the

-moving part of the object with which it is engaged, thereby obviating the liability of the bolt becoming loose.

A further object is to provide a bolt of this character which may be readily adjusted to take up lost motion due to wear or other causes, and by means of which the use of washers may be dispensed with.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side view of a bolt constructed in accordance with the invention; Fig. 2 is a longitudinal sectional view of the same; Fig. 3 is a perspective view of the cap member ofthe bolt looking toward the inner end of the same; Fig. 4 is a similar View of the opposite end of the bolt; Fig. 5 is a sectional view through the blades of a pair of shears showingone application or use of the bolt.

45., My improved bolt comprises an outer casing member '1 which is formed in separable sections 2 and 3, said sections having on their inner or engagin ends an adjustable clutch connection sai connection comprising pairs of lugs 4, the inner side edges of WhlCh arepreferably formed at oblique angles. The lugs 4 of the sections 2 and 3 are arranged at diametrically opposite points and the lugs of one of the sections are so arranged with respect to the lugs of the longitudinally,

other seetion that when the ends of said sections are brought together, an interlock 8 81 the sections of the casing. The lugs 4 are preferably of sufiicient length to permit the sections 2 and 3 of the casin to be adjusted thus providing for the lengthening or shortening of the bolt.

The casing member 2 is provided with a head 5 in which may be formed a screwdriver slot 6 or which may be provided with a milled extension 6*, as shown in Fig. 5 of the drawin s, while the section 3 of the easing is provlded with a head 7 in the outer end of which is arranged a countersunk seat 8 the purpose of which will hereinafter appear. In the section 2 of the bolt is formed an interiorly threaded socket 9 while in the section. 3 is formed a longitudinally disposed passage 10 which is extended through thehead of the section and connects with the countersunk seat or recess 7 of the head.

The sections 2 and 3 of the casing are secured together in operative engagement by means of a connecting screw 11, which is adapted to'be inserted? through the passage 10 of the section 3 of the casing and screwed into the threaded socket 9 of thesection 2 of the casing thereby adjustably securing the two sections of the casing together. When the screw is thus engaged wlth the sections of the casing, the head 12 of the be provided betweenscrew will fit into the recess or seat 8 in the head 7. j

A. bolt constructed as herein shown and described may be employed for the same uses or in the same capacity in which the ordinary form of bolt is employed, but is particularly adapted for usei as a pivot bolt or a clamping bolt, and may be used as shown in Fig. 5 of the drawings or as a spindle or axle bolt for childrens carriages invention will be readily understood with out requiring a more extended explanation.

and the minor details of construction may be resorted to without departing from the principle'or sacrificing any of the advantages of the invention, as defined in the appended claim.

Having thus described my iny ention, what 1' claim is:

' yided with A bolt of the character described comprising a casing formed in longitudinally adjustable sections, one of which is proa threaded socket and the other with a smooth boreor passage, heads on the outer ends of said sections, and a connectin screw inserted through the bore of one o 15 said sections and adapted to be screwed into the threaded socket of the adjoining section whereby said sections may be adjustably secured together.

In testlmony whereof. I have hereunto set 20 my hand in presence of two subscribing wltnesses.

LEONARD F. SCHMIDT.
